RFA (Radiofrequency Ablation) and Microwave Ablation

What is RFA (Radiofrequency Ablation) and Microwave Ablation?

RFA, that is, radiofrequency destruction method; It is a treatment used in the treatment of cancer. This method, which ensures the destruction of cancer cells with heat, is accompanied by imaging, like all other interventional radiology treatments. It is used under ultrasound in interventions in the mother’s womb. In this article, we have compiled what you need to know about RFA and Microwave.

What is RFA? Why is it used?

RFA, also known as RF Ablation, is used in some tumoral formations in unborn babies and in the termination of multiple pregnancies with anomalies.

In which pregnant women is RF Ablation Therapy used?

We can list the necessary conditions for performing RFA treatment as follows:

• It is used to reduce the size of the mass in lung tumoral formations such as pulmonary sequestration and congenital pulmonary adenomatoid marformation in the unborn baby.

• It is used in tumors such as sacrococcygeal teratoma.

• It is used to control the heartbeat of a fetus that is about to die, especially in identical twins, and may harm the other baby if it dies.

• It is used if placental tumors such as placental hemangioma cause heart failure in the baby.

What is Microwave Ablation?

Microwave ablation is also known as microwave ablation. It works in microwave logic and has an RFA-like effect. It enables high frequency electromagnetic waves to activate the water molecules in the tissue. In this way, heat is generated and it destroys the tissue in which the probe is located, by burning it.

What is the Difference Between RFA and Microwave Ablation?

RFA and microwave ablation method are generally similar. There are only minor differences between them. We can list these differences as follows:

• RFA uses radio frequency waves, while microwave ablation uses microwave energy.

• The most important difference in Microwave is that better targeted higher energy is used in a smaller area.

• The biggest difference is that the processing time is much shorter in the microwave.

How are RFA and Microwave Applied?

In both methods, the preparation of the pregnant and the application are the same. Only the device used and the processing time differ.

First of all, detailed ultrasound is performed by the perinatology specialist and the anomaly in the baby is detected. If the treatment of this anomaly is suitable for RFA or Microwave treatments, the pregnant woman is prepared for the procedure.

The entire procedure is performed under local anesthesia, that is, while the expectant mother is asleep. After skin cleansing and skin preparation, the area where the procedure will be performed is widely anesthetized with local anesthetic under ultrasound guidance.

The method is done by means of a probe similar to a needle. The probe is placed to the desired area in the fetus under ultrasound. After that, the process is completed in an average of 5-20 minutes.

What are the Complications of ablation treatments?

• Although very rarely, bleeding may occur due to the injury of the veins in the anterior abdominal wall of the expectant mother.

• The operation may fail in rare cases and the desired goal may not be achieved.

• Since the probe used during the procedure pierces the amniotic membrane around the fetus, it may cause membrane rupture and cause water to come. This complication is a risk that can be seen at a rate of approximately 10%.

• Although rare, it can cause infection in the mother or fetus.

• If infection occurs, it may be necessary to terminate the entire pregnancy for treatment.

As it is clearly stated, although all operations performed in the womb can be very beneficial and life-saving, they can also bring great risks. For all these reasons, both the diagnosis and the selection of the appropriate treatment are the most important steps.

  Perinatology examination is the most important in RFA and Microwave ablation treatments in the light of the above. The perinatologist defines the problem of the baby in the womb by making detailed ultrasound. Experienced in this field, Perinatology chooses the most appropriate treatment. The success of the treatment depends on them.

All pregnant women should not neglect to have a perinatology examination twice during their pregnancy, one between 11-14 weeks and the other between 20-24 weeks.
